Rising population, diminishing arable land, declining
non-renewable energy supplies, increasing
awareness of potential environmental degradation,
climate change and variability.
Common need to reach an equilibrium between
the use of production resources and the
preservation of the resources themselves.

…An unknown surface,heed we to forelearn
the winds and varying temper of the sky,
the lineal tillage and habits of the spot, what
every region yields, and what denies.
Here blithelier springs the corn, and here the
grape, there earth is green with tender growth
of trees and grass unbidden.
See how from Tmolus comes
the saffron's fragrance, ivory from Ind,
from Saba's weakling sons their frankincense,
iron from the naked Chalybs, castor rank
From Pontus, from Epirus the prize-palms.
And such the laws by Nature's hand imposed
on clime and clime….
The agricultural system
Agronomic: management for the
optimization of yield quantity and
quality
output
inputs
Climate: growing season
lenght, temperature, rainfall,
radiation, extreme events
frequency
Why the same species grows differently in different
geographic areas ??
Because radiation is differently distributed at global,
regional, local scales.
Radiation is the
growth source
and the modulator
of plant
morphology and
structure
Light intensity
Light quality
Yield performance
Why the same species grows differently in different
geographic areas ??
Because photosynthesis
is sensitive
to temperature
Increase,optimum,decrease
(enzymes degradation)
Because phenological crop
development and lenght of the
growing season are driven by
cumulated temperatures
Why the same species grows differently in different
geographic areas ??
Because of soil type
and of water availability
Objectives of the workshop
To review and recommend appropriate
techniques for agroclimatic characterization
and sustainable land management, including
technologies such as GIS and remote
sensing
Objectives of the workshop
To provide examples of innovative techniques for
sustainable land management, based on suitable
agroclimatic characterization, as documented from surveys
of succesful pilot projects at the national and regional
levels
Objectives of the workshop
To develop a statement of requirements for defining and
quantifying observational characteristics in general and for
specific regions, pertaining to agroclimatic features, land use
management and projected future trends, emphasizing the
adequacy of information needed for application of GIS
technology to agriculture, rangelands, forestry and fisheries
Objectives of the workshop
To make recommendations on the methods to cope with
limitations and weaknesses in the provision and
accessibility of innovative operational technologies at the
national and regional levels
